KETTLE JACKET CLEANOUT AND PASSIVATION PROCEDURES
The following procedure should be preformed at least once every three years to prevent possible corrosion and ensure the optimum life of the kettle.
WARNING:
IMPROPER REFILLING OF KETTLE JACKET WILL RESULT IN IRREVERSIBLE DAMAGE TO UNIT.
DANGER:
WORKING ON MACHINES WITH POWER COULD RESULT IN SEVERE ELECTRICAL SHOCK.
DANGER:
MOLYFILM 315 IS CORROSIVE, AVOID
CONTACT WITH SKIN AND EYES.
DANGER:
AVOID INHALATION - VAPORS FROM
MOLYFILM 315 MAY BE HARMFUL OR FATAL.
DESCRIPTION - Molyfilm 315 inhibits corrosion in stainless steel and copper. A pH buffer is present to assist in maintaining the appropriate pH to assist in corrosion inhibition.
DISPOSAL - Follow all Federal, State and local codes when disposing of product.
SHELF LIFE - Molyfilm 315’s effectiveness will diminish after three years.
REFILL QUANTITIES (ORDERING INFO: 1 Liter Molyfilm 315 Rust Inhibitor - Part#
IMPORTANT: To ensure satisfactory mixing follow the MIXING / FILLING PROCEDURE described below.
Kettle Size | Volume of Water | Volume of Molyfilm 315 | ||
| U.S. Gal. | Liters | oz. | cc (ml.) |
6 U.S. Gal. | 1.6 | 5.8 | 2.1 | 61 |
12 U.S. Gal. | 2.2 | 8.3 | 3 | 88 |
MIXING / FILLING PROCEDURE

2.In a separate container mix 1/2 gallon of the required volume of water with the total required volume of Molyfilm 315.
3.Pour mixture into kettle.
4.Pour the remaining required volume of water into kettle.
DANGER:
PRESSURE RELIEF VALVE WILL
EXHAUST HIGH TEMPERATURE STEAM.
CONTACT WITH SKIN COULD RESULT IN
